Abstract

ObjectivesThe effects of vascular occlusion on recovery of physiological and neuromuscular markers over 24 h, and hormonal reactivity to subsequent exercise were investigated.DesignCounterbalanced, randomised, crossoverMethodsAcademy rugby players (n = 24) completed six 50-m sprints (five-min inter-...
